Introduction
ColdStream displays the intermediate designs for running and finished cases of type 'Standard design' under the 'Design evolution'-tab. Opening this tab for a case of interest, visualizes the progess of the standard design. At any given moment, you'll be able to see how many iterations have been performed by ColdStream.
The following chapter will delve deeper into the information displayed in the 'Design evolution'-tab. The last chapter will explain how to view the information for a specific iteration.
Design evolution tab
There are two types of graphical representations present in the 'Design evolution'-tab:
- An overall design performance graph: displayed at the top of the page
- Target specific graphs: for each of the targets, a separate graph displays the their evolution at the bottom of the page.
The first graph visualizes the overall performance evolution of the optimization across several iterations. The overall performance of the designs is determined with respect to the case setup and the objectives for the case. The different colors represent the feasibility of the design:
- Green: best feasible iterations
- Blue: feasible iterations
- Red: infeasible iterations
The target specific graphs showcase the same information but for each target individually. Comparing these grapsh with one another reveals which target dominates over the other. The legend is exactly the same as enumerated above.

Selecting specific iterations
At the top of the page, one can select a specific iteration of interest by dragging the slider to the prefered iteration and pressing the 'Select'-button next to it. A diamand shaped marker in the different graphs visualizes which iteration you're selecting. All other iterations are showcased using circular markers.
Once an iteration is selected, a GUI appears for each design subregion displaying the heatsink(s) ColdStream used during this iteration. Additional information about the displayed heatsinks will also be shown:
- What type the heat sink is: pins or fins
- How the pins or fins are manufactured
- The number of pins/fins
- Geometrical information aboud the pins/fins
